Some days it starts some days it doesn’t. I had battery replaced but still the same problem.

Hi,

When it doesn't start, does the starter engage and turn the engine and the engine just not start? Or does the starter not engage at all?

Let me know that. Also, take a look through this link. You may find it helpful. It explains the most common causes of a crank no start condition.

Here is a link that discusses how to check/repair a starter not working:

Let me know exactly what happens when it doesn't start. That will help me eliminate things.

Take care,
Joe

It sounds like it is trying to start but just can’t get over that last bit. mechanic plugged it into diagnostics and said it found nothing wrong?

Hi,

If there is no code, then we need to start simple. I need you to check both for spark and fuel to the engine. Simply see if the engine starts for a couple of seconds using starting fluid. If it does and then stalls, we know it's a fuel related issue. If nothing changes, then it's likely ignition related.

Here are two links you may find helpful. They explain how to check for spark and fuel.

Try that and let me know the results.

You are very welcome. If possible, record it when you are trying to start it and upload it for me to hear. It may help me make a better diagnosis.

Take care,
